ProSeries lists minimums for computer configuration but that does not take into account how many open programs, how large the file size, etc.  Typically 32gb would be more than enough.  I'd look at your Task Manager in Windows (CTRL-ALT-DEL) and look at % Memory usage in the Processes tab.  If the % is high you have an issue and need to close stuff.  I'd also look at your Windows startup processes and see what programs automatically open when you boot up.  I've found so many extraneous things opening I had no clue.  Windows also tells you if these items have a low or high memory usage.  You can then go to the next tab in the Task Manager of Performance.  After that, call your IT person.  Possible some of your 32gb of memory has gone bad.  IF - computer memory is your problem, versus a ProSeries issue.
